what i don't get is why you don't consider people wanting to buy bitcoins to actually use them as a currency and spend them ?
Seriously? You think 200 little vendors is going to drive the current market cap?
It's not the vendors... look...
The supply of bitcoins is fixed. Some portion of all the coins created up until this point are for sale.
The demand for bitcoins is growing. With all of the recent news about Bitcoin, many new people have been finding out about it and wanting to buy bitcoins.
Steady supply + increasing demand = rise in prices
Exactly people need to stop trying to "fix" the market. It either lives or it dies, if you try to fix the market, it dies.
What you don't get is that even an individual trying to "fix" the market (a claim for which you have shown no evidence) is
part of the market.
